Background

Proficiency with reading and writing is fundamental to being a good student and a good worker in nearly any field

Student writing, however, typically is directed towards the instructor solely for the purpose of assessment (Britton et al. 1979)

Writing Process

Writing process consists of 3 metacognitive actions:

Planning

Translating

Revising

For proficient writers, the revision process should allow for assessment of writing, finding of errors, and formulating changes that lead to both expression of understanding and understanding of the subject matter itself

Experiment

Year 1:

Two papers assigned

First paper on free form inquiry-based, 2 week lab, driven by students’ own questions

Students given 2 weeks to write paper

Paper graded, returned, students given opportunity to revise

Second paper on structured inquiry-like experiment, 2 week lab on fruit fly mating behavior and genetics

Students given 2 weeks to write paper; no rewrite

Abstract

Mean scores on the abstract between the first and second replicates. There was no statistically significant difference t(10) = 0.43, p > 0.05, between the mean score on the first paper replicate and the second.

IntroductionMean scores on the introduction sections between the first and second replicates. There was no statistically significant difference between the mean score on the first paper replicate and the second t(10) = 0.67, p > 0.05

Materials & MethodsMean scores of the materials and methods sections between the first and second replicates. There was no statistically significant difference between the mean score on the first replicate and second replicate t(10) = 0.99, p > 0.05.

ResultsMean scores of the results section in the first and second paper replicates. There was a significant increase in the mean score from the first to second replicates t(10) = 2.15, p < 0.05.

DiscussionMean scores of the discussion section in the first and second paper replicates. There was a statistically significant increase in the mean score from the first to second paper replicates t(10) = 2.37, p < 0.05.

ReferencesMean scores of the references section in the first and second replicates. There was no statistically significant increase in the mean score from the first to second paper replicates t(10) = 0.32, p > 0.05.

Why So Little Improvement?

College students aren’t really proficient writers – they are novice writers

Revision of work by novice writers tends to just have superficial changes (Butterfield et al. 1994; De la Paz et al. 1998)

Word changes, spelling corrections, grammar corrections

These have minimal effect on quality of text

Experiment

Year 2

Break down scientific writing process further

Poster,

then paper

Poster submitted prior to printing, revised, then printed

Students graded each other’s poster so that they could “see” faults in written sections

Students then reflected on how their poster experience would inform their paper writing

Paper then written on fruit fly experiment

Explanations Provided

Grading Rubrics Given

Reflection Assignment

Results Still Being Assessed

BUT … instructor’s perception is that papers

were more poorly written

using this method than Year 1

method, perhaps because of haste
